Arrival by arrival
How late DL 563 runs when it is late
DL 563 often beats the schedule: 98 of 284 completed flights, 35%, arrived 15 minutes or more early. The 94 late arrivals split 29 under half an hour, 21 between 30 and 60 minutes, and 44 an hour or more.

Share of 284 completed flights by arrival against schedule.
12 of 84 late departures made up the time and arrived on time, 14% of them. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCI.
The worst days
Worst days for DL 563
The latest arrival of the period was on 17 November 2025, 11 hours 26 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 November 2025 | 11 hours 26 minutes | Carrier |
| 27 August 2026 | 7 hours 3 minutes | National Airspace System |
| 20 January 2026 | 5 hours 43 minutes | Carrier |
| 24 September 2025 | 5 hours 3 minutes | Carrier |
| 6 July 2026 | 3 hours 41 minutes | National Airspace System |
Delay causes
Why DL 563 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,710 reported delay minutes.
- 42%Carrier
- 29%National Airspace System
- 27%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,231 of the 7,710 delay minutes reported here. The split is drawn from 7,710 delay minutes reported on DL 563.
Cancellations run at 7.17%, against 1.89% nationally. That is about one flight in fifteen cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
15.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 1,107 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on four other city pairs in the data, including MCI to LGA (51), ATL to DCA (16) and DCA to ATL (16), but none flew often enough under DL 563 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to MCI only.
One caution: this is a thin sample. 307 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking DL 563
For a booking, the cancellation rate is the figure to plan around on DL 563: 7.17% of its 307 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
